Specification of Letters Patent.

Patented July 20, 1920.

Application filed April 15, 1920. Serial No. 374,209.

To all whom it may camera:

Be it known that I, GAETANO ARTURO Gnooco, a subject of the King ofItaly, residing at Rome, in the Kingdom of Italy, have invented certainnew and useful Improvements in Perforating-Machines for Bank-Drafts andother Documents, of which the following is a specification.

The present invention refers to perforating machines for bank drafts andother valuable papers of that class in .which numbers and words arefirst prepared singly by rotating the lettered or numbered disks of asetting device which is then brought in such position as to cause groupsof pins or punches to pass through and to pierce the paper leaving insame a number of holes arranged in such manner as to show the figures orthe letters which are to be impressed.

In perforating machines of said class there is a punch plate carrying agroup of pins spaced at equal intervals within a rectangle out of whichare composed the figures and the letters every time they are required bylowering or pushing against them the drums of the setting device, thedrums having holes allowing free passage to the punches whlch must notbe lowered, while the other punches forming the letter or number are,pushed through the paper.

The invention has the object of simplifying the construction of suchmachrnes by substituting for the drums of the setting device withperforated periphery, blocks of disks with conveniently indentedperiphery, which, when put together form a drum showing in relief thecharacters and around them recesses within which may enter the puncheswhich must not be depressed.

In the drawing annexed hereto, whlch illustrates this invention:

Figure 1 shows, on an enlarged scale, the arrangement of the punchcarrying plate with the pins for a single drum the figure 8 being shownby way of example in sol1d black.

Fig. 2 shows a complete punch carrymg plate for a group of elevencharacters.

Fig. 3 shows in a section a group of pins While the machine is about topierce th paper.

Fig. 4 is a view of the complete apparatus set in a lateral elevation;

Figs. 5, 6, 7 struction.

Fig. 1 shows in what manner can be obtained for instance, figure 8 froma group of pins comprising seven rows of four pins each: the pins to belowered by the drum of the setting device are marked thereon in solidblack, while the pins shown with a small empty circle are those whichremain lifted and do not pierce the paper.

Fig. 2 device the whole punch carrying plate with the ten figures 1, 2,3, 4, 5, 6, 7, 8, 9, 0 and the character in black.

Fig. 3 is a schematical section showing in which manner works the devicebearing the set of pins; some of the pins 1 are lowered under the pushof the parts in relief of the disk 2, while the others remain liftedengaging the recesses 3 of the disk.

The pins are provided in their middle with a shoulder 4 which preventsthem from getting out of the punch carrier, limiting their strokebetween the two perforated plates 5, 6 by which they are controlled. Theframe with the aforesaid metal plates is movable and is kept up by meansof suitable springs while plates 8 and 9 within which the paper to beperforated is introduced, and which they also bear holes for the passageof the pins, are fixed at the base plate of the apparatus.

The general arrangement of the machine is schematically shown in Fig. 4.It consists of a base plate 10 whereon are arranged the guiding plates 8and 9 and the frame 5, 6 of the punch carrier. Upon a pivot 11 ismounted a handle 12 bearing the setting and printing device. This mayconsist of a single drum 13 and in this case it is necessary to add oneof the usual devices for the forward movement of the paper sheet alongthe space corresponding to a figure before passing to the following inperforating one figure afteranother; said device is not shown in thedrawing. I

The machine may instead have a plurality of drums with punch holdersextending under all the drums; in such a case the sheet of paper remainsfixed and the number composed beforehand is pierced at one singlestroke.

In order to facilitate the task of the operator in composing the number,the drums have some intervening spaces 14: between and 8 show details ofthe conthe different figures or letters where are engraved thecorresponding figures or letters, but on the side diametricallyopposite, and the latter appear 5 ing 15.

Another form of the apparatus is sche- T matically represented in Fig. 5which shows their figures are formed by thin disks 16 set at intervalswhich penetrate between the fixed plates 17, of the punch carrier andeach one of them is made in such a way as 20 to press on the heads ofthe pins which must be lowered. Disks of a smaller diameter are mountedon the axis of the drum between the preceding disks and hold them at thedistance required;

'25 :In Fig. 8 th drum is shown formed of a plurality of theirjuxtaposed plates having behind an opposite open-.

In this form of execution the drums with their edges cut off or rabbetedto form the projections'and recesses. r

A spring actuated ball 19 stops exactly the drums in the proper positionfor'printin e'ach'letter or number.

t will be easily .understoodthat the disks 2 may be ,cut in greatquantityand even from hard metal plates as steel and the like, withgreat speed and economy.

Claimsv 1. In a perforating machine, a drum for operating theperforating pins having peripheral pro ect1ons and recesses, sa1d drumbeingformed of a plurality of thin disks.

2. In a perforating machine, ardrum for operating the perforating pinsformed of a plurality of thin juxtaposed disks having their edges cutoffor rabbeted toformpe- 3 ripheral projections and recesses. V

In testimony" whereof I' have afiixed my signature in the presence oftwo witnesses, at Rome this 22nd day of March, 1920. I
